Title: Improvements in and relating to friction driven steplessly variable speed gears
IPC: F16H15/40
Filed: 1956-06-09
Abstract: 809,136. Variable -speed friction gear. ANDREWS, W. R. June 4, 1957 [June 9, 1956; June 19, 1956], Nos. 17903/56 and 18870/56. Class 80 (2). A variable ratio friction gear comprises a pair of discs 13 on one shaft 12 between which projects a disc 6 on another shaft 3, the axis of which lies in a plane parallel to that of the shaft 12 but is inclined with respect to that axis to form a pair of V-shaped gaps containing friction balls 17 or convex rollers urged towards the apices of the gaps to make friction driving contact with the discs, and adjustable towards or away from the shaft axes to vary the ratio. The angle of the V-gaps is substantially equal to the minimum angle of friction. As shown, the shaft 3 is the input shaft, 12 an intermediate shaft, and a further pair of balls 17, adjustable with the first pair, transmit drive to a second disc 11 fast on an output shaft 7 parallel to the input 3. The input and output shafts 3, 7 may both carry paired discs such as 13, the intermediate shaft 12 then being a single disc. The output shaft 7 is restrained against axial movement but the other shafts 3, 12 have axial freedom to permit equalization of traction pressure provided by springs 32 acting on ball cages 18 in conjunction with torque-responsive pressure acting to force one ball 17 of each pair more deeply into its V-gap. The ball cages 18 support the balls 17 in grooves 22 and apply pressure to them through rollers 24 or ball bearings. Where convex rollers are used instead of balls 17 these may be rocked about their axes castor-wise to provide different friction tracks as the ratio is changed. For ratio shift the cages 18 are traversed along grooved guides 29 by an axially-fixed adjusting screw 40 threaded into a nut 38 on a cage, the two cages being tied together by bolts 20 secured to one cage and freely engaging slats in the other.

Abstract: 421,731. Operating railway points. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Bone, H. L.; c /o Union Switch & Signal Co., Swissvale, Pennsylvania, U.S.A.) June 29, 1933, No. 18493. Convention date, July 1, 1932. [Class 104 (i)] Mechanism 13 for operating and locking spring- controlled trailable points 2, 2a comprises a casing 19 in which is mounted a sliding plate 26 adapted to be moved by a hand lever 30 through a pinion 33 and a rack 27 on the plate. The plate has a cam slot 28 engaging a roller 34 which is connected to the head rod 6 of the points by crank mechanism 36, 37, 37<a>, rod 9, and spring- return device C. The locking bar L is connected to the front rod 5 of the points and has a notch adapted to be engaged by a locking plunger 39<e> carried by a sliding frame 39, in the casing 19. The frame is forced towards locking position by springs 39<n> mounted on bolts 39<l>, 39<m> which are screwed into holes 39<f>, 39<h> in the end 39<c> of the frame, and pass through holes 39<g>, 39<k> in the other end of the frame and also through lugs 42, 43 carried by the plate 26. When the points are to be reversed from the normal position of Fig. 1, the lever 35 is turned over to the dotted position, and during the first part of this movement, the lugs 42, 43 on the plate 26 engage the end 39d of the frame 39 and withdraw the plunger 39<e> from the locking bar L. During the next part of the movement of the lever 30, the cam slot 28 in the plate 26 moves the roller 34 and so reverses the points. When a train trails the points, the first effect is to deflect the heel of the points sufficiently to cause the tie-rod 8 to withdraw the locking plunger 39<e> from the bar L by means of linkage 59, 57, 56 and a bolt 54 engaging the locking frame 39. The points are then free to be moved by the train to reverse position. After the train has passed, the points are slowly returned to normal by the spring device C against the retarding action of a buffing device D. Signal lamps 5<1>, 5<2> indicate whether or not the points are closed and locked, and are controlled by means of a lever 66 having a projection 671 engaging a recess 68 in the plunger 39' and a cam face 69 adapted to coact with a cam 70 on the plunger. If the plunger is not in locking position, the lever is rocked to open contacts 78, 79 in the lamp circuit to show a red light. If the points are not closed, a detector rod 63 connected to the points opens contacts 84, 85 in the lamp circuit to show a red light. In another form a signal is mechanically operated by the lever 66. In another form, the points are connected solely by two spring members C.

Abstract: 672,722. Instruments for deaf persons. AMPLIVOX, Ltd. July 13, 1949 [Jan. 20, 1949], No. 18529/49. Class 40 (iv). In a bone - conduction receiver comprising a pressure member c which is surrounded by a flexible soundshield d and vibrated by a magnet system mounted in a pot member i, substantial changes in vibration intensity due to variations in pressure applied to a cylindrical receiver casing e are prevented by slidably mounting the pot member within the casing so that it reacts against a helical spring h, and by forming the flexible shield so that its stiffness increases with deformation. The pot member is supported by a felt ring m and carries a magnet f and a diaphragm b to which is attached an armature a and the pressure member c. The flexible cover, which by preventing air conduction of sound enables the receiver to be used in audiometer comparison tests of bone and ear sound conduction, is tapered as shown to provide the variable stiffness effect and may consist of layers of different rigidities, the outer layer being made of soft rubber or synthetic material.

Title: Improvement relating to brakes in or for power presses and the like machines
Inventor: RIDLEY HARRY HEYWOOD
IPC: F16D65/28
Filed: 1968-04-19
Abstract: 1,270,654. Brakes; dashpots. BROUGHTON ENG. Ltd. 21 April, 1969 [19 April, 1968], No. 18610/68. Headings F2E and F2S. An hydraulic brake which prevents overshoot of the driving crank of a press comes into operation on over-travel of the crank beyond its normal stopping position (usually top deadcentre) and incorporates means for compensating for fall in retardation with fall in crank-shaft velocity. By this means the crank is brought completely to rest within 30 degrees over-shoot. The crank-shaft 13 of the press is coupled on over-shoot to a damper piston 12 moving in an hydraulic cylinder 11 by means of a catch 14 on the crank-shaft and having a cut-out portion 14a leaving radial shoulders 14b. A plate 17 rotating about the shaft, carries a pivoted latch 15 which is linked to a mechanical guard on the work-table of the press. In the " safe " position of the guard, the latch 15 is in the dotted position 15a in which it is free of the catch 14, but when the guard is open, the latch 15 is in the operative position shown in full lines so that it may engage a shoulder 14b to rotate the plate 17 in a clockwise direction about the crankshaft to operate the damper rod 12. This damper may be as shown in Fig. 2 in which liquid is forced through spring-loaded valve 124. This movement moves piston 130 which in turn moves a further piston 131 against constant air pressure supplied at 133. A resilient buffer 134 may complete the braking. An outlet 149 may be provided to energize an hydraulic brake acting on the fly-wheel or other rotary element of the press (Fig. 9, not shown). In an alternative form of damper, Fig. 3, a piston 212a closes successive outlets 241a-241g to progressively increase the braking effort. A floating annular piston 242 takes up the fluid displaced. An outlet 249 may be provided to feed the fly-wheel brake as already described.
